A therapeutic challenge to maxillofacial surgeons is management of panfacial fractures, especially when treating multiple comminuted bone fractures. One of the most important goals in these fractures is achieve and stablish a correct occlusal relationship of the mandibular-maxillary unit in parallel with the proper positioning of the jaws with the skull base and other facial units. Also, it is important to prevent long-term sequelae such as facial asymmetry, enophthalmos, and mal- occlusion that could be caused by inadequate correction. To achieve all these goals some usual guides of management are proposed as follow: “Bottom to up”, “Top to down”, “outside to inside,” or “inside to outside”. We present 3 cases of Panfacial fracture and the proposed methods were based on different sequences of management with introducing “reference point” as the most intact area to determine the management concept & “confirming point” as the areas that should be reduced and fixed completely. These points act as an orientation aid during surgery and aid to successfully restore the entire face contour and maxillomandibular occlusion and also to improves surgical procedure.

AbstractAutomatic bird detection in ornithological analyses is limited by the accuracy of existing models, due to the lack of training data and the difficulties in extracting the fine-grained features required to distinguish bird species. Here we apply the domain randomization strategy to enhance the accuracy of the deep learning models in bird detection. Trained with virtual birds of sufficient variations in different environments, the model tends to focus on the fine-grained features of birds and achieves higher accuracies. Based on the 100 terabytes of 2-month continuous monitoring data of egrets, our results cover the findings using conventional manual observations, e.g., vertical stratification of egrets according to body size, and also open up opportunities of long-term bird surveys requiring intensive monitoring that is impractical using conventional methods, e.g., the weather influences on egrets, and the relationship of the migration schedules between the great egrets and little egrets.

Recently, deep learning-based techniques have shown great power in image inpainting especially dealing with squared holes. However, they fail to generate plausible results inside the missing regions for irregular and large holes as there is a lack of understanding between missing regions and existing counterparts. To overcome this limitation, we combine two non-local mechanisms including a contextual attention module (CAM) and an implicit diversified Markov random fields (ID-MRF) loss with a multi-scale architecture which uses several dense fusion blocks (DFB) based on the dense combination of dilated convolution to guide the generative network to restore discontinuous and continuous large masked areas. To prevent color discrepancies and grid-like artifacts, we apply the ID-MRF loss to improve the visual appearance by comparing similarities of long-distance feature patches. To further capture the long-term relationship of different regions in large missing regions, we introduce the CAM. Although CAM has the ability to create plausible results via reconstructing refined features, it depends on initial predicted results. Hence, we employ the DFB to obtain larger and more effective receptive fields, which benefits to predict more precise and fine-grained information for CAM. Extensive experiments on two widely-used datasets demonstrate that our proposed framework significantly outperforms the state-of-the-art approaches both in quantity and quality.

Management Concept

There are few activities so susceptible to the impacts of the macro environment as tourism. In conditions of growing uncertainty, the importance of strategic management is steadily increasing. By studying the environment, by anticipating the future development and implication of trends on enterprises, and by developing appropriate strategies at a number of levels, strategic management seeks to actively influence the increase o f competitive advantages o f both the tourist destinations and tourist enterprises. The term “strategic management” implies a set of management decisions and actions that determine the long-term operations o f enterprises within the management system of tourism: guiding the enterprise by anticipating crucial environmental impacts and internal factors. This management concept is based on the assumption that making properly oriented strategic decisions minimizes the negative effects of the environment and creates strategic advantages for enterprises that can be capitalised only in the medium and long term (Čizmar S. (2001) Strateško upravljanje u funkciji učinkovitog razvoja turističkog ugostiteljstva u Hrvatskoj, doctoral dissertation, University o f Zagreb, Faculty of Economics, Zagreb, p. 3). It represents an integrated approach to strategic management that is the most acceptable for the development of Croatian tourism, as long-term positive results, in both market and financial terms, can be achieved by enterprises within the tourism management system of Croatia only by applying an integrated approach to strategic management, by horizontally and vertically linking the elements of all subsystems of the entire management system and by creating partnering relationships. The Croatian model of strategic management should involve the economic optimisation of all subsystems and systems by establishing efficiency not only across all subsystem elements, but through the system as a whole as well. The level of growth in entrepreneurship and innovations will determine the intensity and speed of positive development changes. These changes will also depend on establishing management responsibilities throughout all segments and managements levels of all subsystems, as well as tourism as an integral system. This paper deals with the issues of strategic management at a micro level with special emphasis on the development of responsibility for managing performance and capital investments.

Persistent Depressive Disorder

Background: Persistent depressive disorder (PDD) is a chronic problem that is more prevalent among women than men. Various studies have revealed that these people experience many problems in their interpersonal relationships, which increase their suffering. Objectives: The present study was done to identify how people suffering from PDD experience interpersonal relationships that often seem troubled and broken. Methods: A phenomenological approach was adopted for this qualitative study. For this purpose, in-depth interviews were conducted with 21 individuals with PDD, focusing on exploring their experience and suffering in interpersonal relationships. All interviews were recorded and transcribed, and the transcripts were analyzed using Giorgi’s phenomenological descriptive method. Results: In general, five main themes and 16 sub-themes emerged. The main themes were: (1) Feeling empty of love and compassion; (2) feeling ignored; (3) ignoring others’ needs, conditions, and suffering; (4) feeling of being annoying to others; and (5) feeling confused and helpless in relationships. Conclusions: It seems that all five themes convey the message that these individuals demonstrate less skill in feeling compassion and receiving it from others. Therefore, it appears that long-term compassion-based interventions can effectively reduce the interpersonal suffering of these individuals. It should be noted that although these themes have commonalities in different cultural contexts, the culture can influence the content and intensity of these feelings.

Bisphosphonates are potent anti-resorptive agents that have the potential to adversely affect bone healing in equine athletes, and normal bone adaption in young racehorses. A concern exists that bisphosphonate inhibition of normal bone metabolism could lead to increased bone fractures during high-intensity exercise. We found only a single report describing concentrations of tiludronate in the bone of horses, and no studies describing clodronate. Knowledge of the residence time in bone could allow for a better understanding of the long-term effects of these compounds. Our objectives were to develop a method for detection of bisphosphonates in bone and add to the limited information available regarding the disposition of these drugs in the bone of horses. Two horses received clodronate and 2 tiludronate disodium. Postmortem collection of bones and teeth occurred either 4 or 30 d post drug administration. Additionally, postmortem blood, synovial fluid, aqueous humor, and bone samples from racehorses with various histories of bisphosphonate administration were collected, and concentrations determined using the developed LC-MS/MS method. Bisphosphonates were detected in bones and teeth tested at 4 and 30 d. In a postmortem sample, clodronate was detected in bone from a horse with reported administration 18 mo prior; clodronate was not detected in other sample types collected from this horse. Bisphosphonates reside in bone for extended periods of time, which could lead to potential long-term effects, increasing the potential for bone fractures in young and/or athletic horses.
